More accurate and flexible attitude maneuvering capability is demanded for extending applications of CubeSats. In this seminar, an autonomous conditionbased switching method from among a family of control and estimation algorithms is introduced to extract required attitude maneuvering performance with lowprice sensors, small-sized actuators, and low-powered processors. A design of hybrid automaton for multialgorithmic hybrid ADCS is proposed by defining a set of operative modes, domain mapping, set of edges, and guard mapping. In addition, experimental analysis is pursed using CubeSat Three-Axis Simulator (CubeTAS) to simulate a frictionless and torque-free environment. By implementing the hybrid ADCS on the real-time test bed, the performance of the proposed method is validated with real sensors, actuators, and computing resources.
